Presently there is a little information that relates to heat shield systems.  Also this information is not certain in so many cases.  The main reason is that accurate calculations for measuring the sacrificing rate of various materials have not been obtained yet.  Additionally, the real scale test has two disadvantages: high cost and low flexibility, and for each case we must perform a new test...

approximately 25% of all oral cavity carcinomas involve the lips, and the primary management of these lesions is complete surgical resection. loss of tissue in the lips after resection is treated with a variety of techniques, depending on the extension and location of the defect. here we review highly accepted techniques of lip reconstruction and some of new trials with significant clinical res...

BACKGROUND The summit of the left ventricle (LV) is the most superior portion of the epicardial LV bounded by an arc from the left anterior descending coronary artery, superior to the first septal perforating branch to the left circumflex coronary artery. Ventricular arrhythmias (VAs) originating from this region may present challenges for catheter ablation. METHODS AND RESULTS We studied 27 ...

In this work we report on progress in the development of models for a Micro-Pulsed Plasma Thruster (μPPT) and its exhaust plume. As a working example we consider a μPPT developed at the Air Force Research Laboratory. This is a miniaturized design of the axisymmetric PPT with a thrust in the 10 μN range that utilizes Teflon as a propellant. The plasma plume is simulated using a hybrid fluid-PIC-...

A 60-year-old male with a history of prior ablation of typical cavotricuspid isthmus-dependent atrial flutter presented to us with recurrent palpitations. The surface 12-lead EKG was consistent with atrial tachycardia, for which an ablation was planned. The patient was found to have multiple marcroreentrant left atrial tachycardias utilizing areas of scar as substrate. Isthmuses of tissue with ...

Ablation of accessory tracts in the posteroseptal region can be challenging, as illustrated by these 2 cases. Familiarity of the anatomy of this region and recognition of the ECG patterns can help identify the AP origin and potentially improve success rates of ablation. The isoelectric initial preexcited QRS complex with rSR’ pattern in lead V1 of the surface ECG but not the relatively earlier ...

Introduction: The ablation technique is one of the important therapeutic interventions for treatment of AV Nodal tachyarrhythmia. Different animal models have been developed to study the effects of ablation on the functional interanodal structure. The aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbi...
